Title: Force measuring instrument
IPC: G01G21/00
Filed: 1961-12-11
Abstract: 947,120. Force-measuring devices; weighing apparatus. C. JOHNSON. Dec. 11,1961 [Jan. 10, 19611, No. 44182/61. Headings G1N and G1W. In a fast-response cantilevered-parallelogram weighing apparatus having a loading platform 70, supported on a wall 20 by a crossed-spring (72,74) flexure pivot, and a spring 166, joined by a bar 136 to the deflectable end of platform 70, the latter carries an Invar steel rod 230 (having negligibly small coefficient of thermal expansion) which supports (see Fig. 4) an armature core 244 inside windings 200 of a differential transformer giving load-varying output. The support for the armature core 244 includes a threaded rod 242 of magnesium or other metal having a high coefficient of thermal expansion and a threaded adjusting sleeve 238 of brass or other metal having a lower coefficient of thermal expansion. By suitably adjusting the effective lengths of magnesium and brass in the armature support, variation with temperature in flexibility of the platform 7 and spring 166 resulting, for example, in increased deflection, can be compensated by a corresponding expansion of the armature support. The differential transformer unit is sealed from ambient external fluid, a bellows 252 surrounding rod 230 being joined to the casing 30 and the platform 70. The deflection of platform 70 is limited, in accordance with the strength of the flexure plates 7 2,74, by an exchangeable collar 118. The range of measurement may be varied by altering the effective length of spring 166 using an adjustable clamp 174 a series of holes 62 being provided in the base of the apparatus for the bolts 176<SP>1</SP>. In other embodiments, two or more pivoted loading platforms are provided cascade-fashion one over the other, the upper one transmitting its load to the one beneath at a position intermediate its ends to give a reduction of the deflecting moment by a predetermined proportion thus enabling very large loads to be measured. The point of forcetransfer may be variable and additional platforms may be disconnected if desired. Specification 829, 252 is referred to.

Abstract: 1,156,499. Separating hydrocarbons. LEUNA-WERKE " WALTER ULBRICHT ", VEB. 3 Oct., 1967, No. 45017/67. Heading C5E. In a process for the separation of hydrocarbons from hydrocarbon mixtures by adsorption or natural and/or synthetic molecular sieves, followed by desorption and accompanied by a rinsing process if necessary, at a temperaure above 250‹ C., the desorption is carried out with a mixture of water vapour and ammonia and/or if aqueous hydrocarbons are present the adsorption and rinsing are carried out in the presence of ammonia. In Examples (1) a gas oil containing less than 10 ppm of water is adsorbed on a Type 5A molecular sieve and desorbed with 5% aqueous ammonia; (2) a mixture of benzene and heptane is separated by desorption with 2% aqueous ammonia; and (3) a gas oil containing 150 ppm of water was adsorbed on a Type 5A sieve in the presence of ammonia, and desorbed with n-pentane. A comparative example involving desorption with aqueous n-propylamine is also given.

Abstract: 997,229. Automatic exchange systems. WESTERN ELECTRIC CO. Inc. Dec. 21, 1961 [Dec. 23, 1960], No. 45788/61. Heading H4K. In an arrangement at a PBX which enables an outside subscriber to select a wanted extension by dialling, relay A responds to ringing current on an incoming line 107, 108 and through relay A<SP>1</SP> shunts resistor 122 across the line to trip the ringing. Relay B operates and switches the line to relay S which energizes followed by S1 and, after a delay determined by a thermistor 112, by D, the latter supplying dial tone. As the central office is in a talking condition, dialling impulses produce small amplitude A.C. pulses on the line 107, 108, and these are amplified and reshaped to control relay P which repeats them to the PBX switch train. A switch 505, 506 advances a step for each digit, and at the conclusion of dialling connects up relay T<SP>1</SP> which connects the incoming line through condensers 120, 121 to the talking wires 204, 205 of the switch train, ringing or busy tone being returned. Relay S is diconnected by relay T which is connected up by polarized relay C when the called party replies. Release by the called party restores the circuit to its normal condition with relay A connected to the incoming line so that a call can be transferred to another extension by fresh dialling. A 4-stage transistor amplifier for dealing with the incoming A.C. pulses is described with reference to Fig. 3 (not shown).

Abstract: 1,120,604. Box filling machines. S.p.A. FABBRICA ITALIANA MACCHINE AUTOMATICHE. 1 Nov., 1965, No. 46206/65. Heading B8C. Articles 66 are arranged in a row within a guide (not shown), e.g. of inverted U-shaped cross-section, by means of a first pusher 78, prior to being inserted into a carton 129 by a second pusher arrangement, the transmission ratios governing the relative motions of the pushers, and a means for raising the guide from the formed row being adjustable to suit the number of articles in the row. In the embodiment described the second pusher arrangement comprises a pusher 93, which transfers the rows into a block-assembling station where, when sufficient rows have been combined, a pusher 142 directs the completed block of articles into the carton 129 which is itself then removed by a further pusher 128. The carton is fed automatically from a magazine to the filling position by a suction device, and may be held at various heights relative to the plane 68 of the pusher 142 so as to stack several layers of articles therein. The apparatus may be synchronized with a wrapping machine from which wrapped articles are fed by a conveyer 62 on to an elevator which lifts them singly into the assembly plane 68. Alternatively the row formation may take place in the plane of the conveyer, the elevator raising each completed row to the plane 68 for subsequent block-assembly. Microswitches activate a lever which raises the guide and the second pusher means, when the row of articles in the guide is complete. The transmission ratios are varied by exchangeable toothed wheels (17- 22), Fig. 2 (not shown), connecting shafts (13, 14, 15) which carry cams controlling the various moving parts of the apparatus. A primary shaft (49), driven by a chain from the wrapping machine, also carries certain cams, and transfers the drive to the shaft (14) via bevel gears (47, 48). Spring-biased plates (87, 90a, 91a), Figs. 4, 4a (not shown), press down on and retain the articles within the guide (84) and en route to the block-assembling station. The pusher (93) comprises a blade (92) mounted on a shaft (94), the motion of which is controlled by cam-driven levers so that the blade (92) firstly moves parallel to the assembly plane (68) so as to transfer the row of articles, and then lifts over the guide (84) on the return stroke. Alternatively the blade (92) may swivel relative to the shaft (94) so that on the return stroke it does not interfere with the guide (84).

The spring loading of the plate 18 is arranged so that its increase with deflection is less than the increase in solenoid force with corresponding core movement thus providing for sudden full plate movement. The spring- loading of the valve 9 is, however, initially higher and increases more rapidly with deflection than the corresponding further armature movement, thus providing for slow opening of the valve 9 with increasing solenoid current. Initial spring loading of the valve 9 is adjustable by an anchorage screw 20 located in a well 27 below the outlet passage 17. When the plate 18 is lifted gas flows from the chamber 17 through the annular passage 23 between the rod and the valve 9 and until the valve 9 is lifted flow rate is independent of electrical input to the solenoid.
